4X71T58931-AX Axiom Lenovo Compatible 16GB PC5-44800 DDR5-5600 288-pin SDRAM UDIMM

4X71T58931-AX Overview

The Axiom is a 16GB DDR5-5600MHz (PC5-44800) Non-ECC Unbuffered UDIMM, engineered as a 100% guaranteed compatible replacement for the Lenovo factory original part (4X71T58931). Tailored specifically for Lenovo ThinkCentre and IdeaCentre desktops, this 288-pin module operates at a power-saving 1.1V, moving communication bottlenecks out of the equation with a massive leap in data transfer speeds over older memory generations.
To ensure peak performance under heavy compute cycles, the module shifts voltage regulation directly onto the stick via an onboard Power Management Integrated Circuit (PMIC) while utilizing native On-Die ECC to protect internal cells against random data corruption. This plug-and-play upgrade delivers the high-velocity bandwidth, thermal efficiency, and factory-level reliability required for smooth multitasking, data-heavy office applications, and mainstream content creation.
